Corian can be cut with any type of saw. I use a band saw for rough cuts and a scroll saw for more detailed cuts. A standard jewelry saw will work, but it takes a long time and then students usually hold the saw at an angle and really mess things up. Then you can use regular lathe tools and turn it on the lathe to shape the outside of the rings. I use spade bits to drill larger holes for fingers, then I use a drum sander on my flex shaft tool to to shape the finger hole to the exact size. I also use the lapidary grinders if there is any significant shaping that needs to be done. Then I also use high speed cutting burs to set stones, or carve details into it.
